Objective To understand the changes in self-rated health among middle-aged and elderly individuals in China and the influencing factors,providing a reference for improving health and promoting healthy aging.Methods Using data from the China Health and Aged Care Tracking Survey(CHARLS)from 2011 to 2020,this study analyzed 3595 middle-aged and elderly individuals(≥45 years old)who participated in all five rounds of the survey from 2011 to 2020.Univariate analysis and multinomial logistic regression were employed to analyze the influencing factors of self-rated health changes.Results Among the 3 595 middle-aged and elderly individuals,26.54％reported an increase in self-rated health,28.40％reported a decrease,and 45.06％reported no change.The multinomial logistic regression results indicated that compared to those with unchanged self-rated health,individuals whose self-rated health declined were more likely to have an increased number of Activities of Daily Living(ADLs),a higher number of chronic diseases,not engaging in at least 10 minutes of light physical activity per week,and a decline in life satisfaction levels.The odds ratios for these factors were 1.415(OR=1.415,95％CI:1.181～1.694),1.479(OR=1.479,95％CI:1.225～1.785),1.454(OR=1.486,95％CI:1.172～1.804),and 1.263(OR=1.237,95％CI:1.043～1.530),respectively.In contrast,individuals whose self-rated health improved,compared to those with unchanged health,were more likely to report an increase in life satisfaction levels,while an increase in ADLs and chronic diseases negatively impacted self-rated health improvement.The odds ratios for these factors were 1.698(OR=1.698,95％CI:1.425～2.023),0.769(OR=0.769,95％CI:0.646～0.915),and 0.689(OR=0.689,95％CI:0.549～0.865),respectively.Conclusion From 2011 to 2020,the self-rated health of middle-aged and elderly individuals in China has slightly declined,with a focus on improving physical health status,increasing physical activity,and addressing mental health as key areas for enhancing self-rated health among the elderly in China.

OBJECTIVE To optimize the water extraction technology for Kaixin granules. METHODS UPLC-MS/MS method was established for the simultaneous determination of ginsenoside Rg1， ginsenoside Re， ginsenoside Rb1， tenuifolin， polygalaxanthone Ⅲ and 3， 6′-disinapoyl-sucrose. An orthogonal test was designed with extraction times， extraction duration， and the volume of added water as factors. Using the contents of the aforementioned six indicator components and the extract yield as evaluation indexes， analytic hierarchy process-entropy weight method was employed to determine the combined weights of each indicator. Subsequently， process optimization and validation were conducted by integrating grey relational analysis （GRA） and back propagation （BP） neural network. RESULTS The water extraction technology optimized by the orthogonal test and GRA was 10- fold water for the first decoction and 8-fold water for the subsequent two， extracting 3 times，extracting for 1 h each time； the average comprehensive score of the validation experiment was 91.10 （RSD＝0.31%， n＝3）. The water extraction technology optimized by BP neural network was extracting 3 times with 10-fold water added each time， extracting for 1.5 h each time； the average comprehensive score of the validation experiment was 95.89 （RSD＝0.73%， n＝3）. Considering practical production requirements， the optimal water extraction technology was extraction performed three times， with 10-fold water for the first decoction and 8-fold water for the subsequent two extractions， with an extraction time of 1 h each. CONCLUSIONS The optimized water extraction technology for Kaixin granules is stable and feasible.

Objective To explore the relationship between serum S100 calcium-binding protein(S100)A4,S100A12 and the infection type and prognosis of neonatal infectious pneumonia(NIP).Methods A total of 300 children with NIP admitted to the Neijiang Second People's Hospital from January 2021 to March 2024 were selected and divided into the bacterial infection group(214 cases)and the non-bacterial infection group(86 cases)according to the types of pathogenic bacteria.Another 150 healthy newborns in the same hospital during the same period were selected as the control group.The levels of serum S100A4 and S100A12 were de-tected by enzyme-linked immunosorbent assay.Pearson correlation analysis was conducted to examine the cor-relations between serum S100A4,S100A12 and procalcitonin(PCT),white blood cell count(WBC),albumin(Alb),and platelet count(PLT).The receiver operating characteristic(ROC)curve was used to evaluate the differential value of serum S100A4,S100A12,PCT,WBC,Alb,and PLT alone and in combination for NIP bac-terial infection.According to the prognosis,children with NIP were divided into the poor prognosis group(63 cases)and the good prognosis group(237 cases).Multivariate Logistic regression model was used to analyze the influencing factors of poor prognosis in children with NIP,and ROC curve was used to analyze the value of each factor in predicting poor prognosis in children with NIP.Results The levels of serum S100A4,S100A12,PCT,WBC,and PLT in the bacterial infection group were higher than those in the non-bacterial infection group and the control group,while Alb was lower than that in the non-bacterial infection group and the control group,the differences were statistically significant(P<0.05).Pearson correlation analysis showed that serum S100A4 and S100A12 in children with NIP were positively correlated with PCT,WBC and PLT(P<0.05),and negatively correlated with Alb(P<0.05).The results of ROC curve analysis showed that the area under the curve(AUC)of serum S100A4 and S100A12 in differentiating NIP infection types was slightly lower than that of PCT,WBC,Alb,and PLT in differentiating NIP infection types.The results of multivariate Logistic re-gression analysis showed that elevated S100A4,elevated S100A12,elevated PCT,bacterial infection,and lung consolidation were independent risk factors for poor prognosis in children with NIP(P<0.05).The AUC of bacterial infection,lung consolidation,PCT,S100A4,and S100A12 for predicting the poor prognosis of chil-dren with NIP was 0.903.It was greater than the AUC predicted separately by bacterial infection,lung consol-idation,PCT,S100A4,and S100A12 levels(Z=9.989,9.460,5.514,4.084,4.376,P<0.001).Conclusion The combination of serum S100A4 and S100A12 with traditional markers has certain discrimina-tory value for the infection types of NIP,and the levels of serum S100A4 and S100A12 are related to the prog-nosis of NIP.

Objective:To analyze the risk factors for herpes zoster complicated by kidney dysfunction and construct a prediction model.Methods:A retrospective analysis was conducted on the clinical data of 150 patients with herpes zoster who were admitted to Hangzhou Third People's Hospital from January 2022 to December 2023. The patients were divided into two groups based on the presence of kidney dysfunction: kidney dysfunction group ( n = 30, with kidney dysfunction) and control group ( n = 120, without kidney dysfunction). The risk factors for herpes zoster complicated by kidney dysfunction were analyzed. The logistic prediction model was constructed. The effectiveness of this prediction model in predicting herpes zoster complicated by kidney dysfunction was assessed using the receiver operating characteristic curve. Results:The differences in gender, body mass index, comorbidities (hypertension and hyperlipidemia), and sites of onset between the two patient groups were not statistically significant (all P > 0.05). The average age of the kidney dysfunction group was (67.74 ± 6.71) years, which was significantly older than that in the control group [(62.32 ± 5.58) years, t = 4.56, P < 0.001]. In the kidney dysfunction group, the proportions of patients with comorbid diabetes, severe pain, large lesion area, high-dose antiviral medication use, and hemoglobin levels < 120 g/L were 46.67% (14/30), 63.33% (19/30), 56.67% (17/30), 46.67% (14/30), and 40.00% (12/30), respectively. These values were all significantly greater than those in the control group [14.17% (17/120), 34.17% (41/120), 31.67% (36/120), 19.17% (23/120), and 10.00% (12/120), χ2 = 15.46, 2.60, 2.10, 9.76, 16.07, P < 0.001, 0.002, 0.035, 0.002, < 0.001). Logistic regression analysis revealed that older age ( OR = 3.023), comorbid diabetes ( OR = 4.315), severe pain ( OR = 3.623), large lesion area ( OR = 3.481), high-dose antiviral medication use ( OR = 4.030), and hemoglobin levels < 120 g/L ( OR = 0.151) were all significant risk factors for herpes zoster complicated by kidney dysfunction (all P < 0.05). Based on these risk factors, the following logistic prediction model was developed: Logit( P) = -8.753 + 1.106 × age + 1.462 × diabetes + 1.287 × pain severity + 1.247 × lesion area + 1.394 × high-dose antiviral medication use + (-1.889) × hemoglobin. The receiver operating characteristic curve analysis indicated that the area under the curve for predicting herpes zoster complicated by kidney dysfunction was 0.904 (95% CI: 0.859-0.937), with a sensitivity of 84.62% and a specificity of 89.04%. Conclusions:The risk factors for herpes zoster complicated by kidney dysfunction include older age, comorbid diabetes, severe pain, large lesion area, high-dose antiviral medication use, and hemoglobin levels < 120 g/L. Based on these factors, the construction of a logistic prediction model can provide a reliable basis for clinical prediction of the occurrence of kidney dysfunction.

Objective:To investigate the efficacy of high-flux hemodialysis in the treatment of stage 5 chronic kidney disease and its effects on nutritional status.Methods:A retrospective study was conducted on 64 patients with stage 5 chronic kidney disease who received treatment at Hangzhou Third People's Hospital from February 2023 to February 2024. These patients were divided into an observation group and a control group according to different blood purification methods, with 32 patients per group. The control group underwent conventional hemodialysis treatment, while the observation group underwent high-flux hemodialysis. Renal function, calcium and phosphorus metabolism, inflammatory factors, and nutritional indicators were compared between the two groups before and after treatment.Results:After treatment, the observation group showed significantly lower levels of serum creatinine [(238.18 ± 64.37) μmol/L] and blood urea nitrogen [(8.35 ± 1.43) μmol/L] compared with the control group [(343.12 ± 75.28) μmol/L, (10.97 ± 1.64) μmol/L, t = 5.99, 6.81, both P < 0.05]. The observation group had lower levels of calcium [(1.65 ± 0.19) mmol/L] and phosphorus [(1.54 ± 0.28) mmol/L] compared with the control group [(2.16 ± 0.23) mmol/L, (2.03 ± 0.36) mmol/L, t = 9.67, 6.08, both P < 0.05]. After treatment, the levels of C-reactive protein in the observation group [(9.72 ± 2.65) mg/L] were lower than those in the control group [(14.98 ± 3.76) mg/L, t = 6.47, P < 0.001]. However, there were no significant differences in hemoglobin, albumin, and prealbumin levels between the two groups ( t = -0.47, -0.16, -0.48, all P > 0.05). Conclusions:High-flux hemodialysis is effective in patients with stage 5 chronic kidney disease. It significantly alleviates the inflammatory state, but it has no notable effects on nutritional status. This approach merits consideration in clinical practice.

Objective:To analyze the proportion of nonobstructive azoospermia(NOA)patients opting for sperm bank donation under different sperm retrieval methods[percutaneous testicular sperm aspiration(TESA),microdissection testicular sperm extraction(mTESE)]and its influencing factors.Methods:Retrospective data from assisted reproductive technology(ART)cycles at the Center for Reproductive Medical,Peking University Third Hospital(from January 2019 to December 2023)were collected.Data-complete ART cycles involving NOA patients and their partners(using the last treatment cycle as the endpoint)were selected.Sperm donation utilization rates were compared across retrieval methods(fresh mTESE,fresh TESA,thawed mTESE,thawed TESA).Log-linear models were used to analyze the rela-tionship between sperm retrieval method and sperm source.Results:Among the 1 730 couples,the over-all sperm donation utilization rate was 12.66％.The highest rate occurred in the fresh mTESE group(23.42％),followed by the thawed mTESE group(5.87％).The rates for the fresh TESA and thawed TESA groups were 5.22％and 0％,respectively.Log-linear analysis demonstrated that sperm retrieval method was significantly associated with sperm source(mTESE:Estimate=4.499;TESA:Estimate=2.780;P＜0.001).Conclusion:The low overall sperm donation utilization rate in ART cycles may re-flect the efficacy of synchronous sperm retrieval ART.The proportion of NOA patients opting for sperm donation was influenced by the retrieval method.Compared with patients undergoing TESA,those under-going mTESE were more inclined to utilize donor sperm after retrieval failure.

Objective To explore the necessity of placing an inferior vena cava filter(IVCF)during interventional therapy for acute lower extremity deep venous thrombosis(DVT)complicated with severe May-Thurner syndrome(MTS).Methods Patients with acute left lower extremity DVT complicated with severe MTS were retrospectively selected and divided into observation group(n=36)and control group(n=36)according to whether IVCF was implanted or not.Pulmonary embolism(PE)was evaluated using compu-ted tomography pulmonary angiography(CTPA).The improvement of the affected limb signs and the occurrence of PE symptoms during treatment were observed.The presence of trapped thrombus was checked during filter removal.The PE incidence,hospitaliza-tion costs,operation time,and hospital stay were compared between the two groups.Results Both groups had a higher thrombus clearance rate after interventional surgery,and the proportion of new small branch PE was lower without significant differences between the two groups(8.3%vs 5.6%,P=1.000).The signs of the affected limbs improved significantly,and no PE-related symptoms occurred during treatment.No obvious trapped thrombus was found when the filter was removed in the control group.Compared with the control group,the observation group had significantly reduced hospitalization costs and operation time(P<0.05).Conclusion For patients with acute lower extremity DVT complicated with severe MTS,omitting IVCF placement during interventional surgery does not increase the risk of PE and can reduce operation time and hospitalization costs.

BACKGROUND: Lung adenocarcinoma (LUAD) is the predominant subtype of non-small cell lung cancer (NSCLC). Damage-specific DNA binding protein 1 (DDB1), as a core protein of the CUL4-DDB1 ubiquitin ligase complex, is involved in the regulation of DNA damage repair, epigenetic modification, and cell cycle checkpoint activation. While the involvement of DDB1 in tumour progression through DNA repair and RNA transcriptional regulation has been reported, its expression and role in LUAD remain to be elucidated. This study aims to investigate the expression and role of DDB1 in LUAD. METHODS: The expression, clinicopathological features and prognosis of DDB1 in LUAD were analysed using databases such as UALCAN, Kaplan-Meier Plotter and GEPIA; The interaction network and enriched functional pathways were constructed by GeneMANIA and Metascape; the correlation between DDB1 and immune cells by combining with TISIDB infiltration was evaluated, and the clustering results of cell subtypes and the expression of DDB1 in different immune cell subpopulations were analysed by single-cell sequencing; finally, tissue microarrays were used to further verify the expression and prognostic value of DDB1 in LUAD. RESULTS: The mRNA and protein expression of DDB1 in LUAD tissues were significantly higher than those in normal tissues (P<0.01), and the high expression correlated with later clinical stage (P<0.001), lymph node metastasis (P<0.001) and poor prognosis (P<0.001). Functional enrichment showed that DDB1 was involved in DNA repair and RNA transcriptional regulation, and TISIDB evaluation revealed that DDB1 was negatively correlated with the expression level of immune cells, suggesting the potential regulation of the immune microenvironment. Single cell analysis showed that DDB1 was mainly expressed in T cells, alveolar macrophages and dendritic cells. Tissue microarrays confirmed that overall survival was shorter in the DDB1 high expression group (P<0.001), and Cox multifactorial analysis showed that DDB1 was an independent predictor of LUAD prognosis. CONCLUSIONS DDB1 is highly expressed in LUAD, which is associated with poor prognosis, and is closely related to tumor immune cell infiltration, and is involved in tumourigenesis and development through DNA repair and RNA transcriptional regulation. DDB1 can be used as a potential prognostic marker and therapeutic target for LUAD.

Objective:This article explores the diagnosis and treatment of a special type of laryngeal foreign body with granuloma in children, providing a clinical reference for standardized diagnosis and treatment. Methods:This article retrospectively analyzes one case admitted to our department and five other cases reported in relevant literature involving a special type of laryngeal foreign body with granuloma in children. It summarizes the clinical characteristics of this disease and explores its diagnosis and treatment. Results:①A total of 6 cases were misdiagnosed and had a long course of illness. Five cases had no clear history of foreign body at the first visit. One case had foreign body history but no foreign body was found. ②The clinical symptoms were diverse, which could be hoarseness, cough, wheezing, dyspnea, or no symptoms. ③A total of 3 cases were diagnosed by laryngoscopy, and 3 cases were diagnosed by laryngoscopy and imaging examination. ④Foreign bodies that were not wrapped in granulomas, were removed first and then the granulomas were treated; foreign bodies wrapped in granulomas were removed after the removal of granulomas. Conclusion:A special type of laryngeal foreign body with granuloma may lack of accurate foreign body history, resulting in long-term retention of foreign bodies, leading to granuloma formation and misdiagnosis. Electronic laryngoscopy combined with CT examination contribute to early diagnosis. Low temperature plasma under endoscope and anesthetic laryngoscope is conducive to the exposure and precise removal of foreign bodies and avoids tracheotomy to a certain extent.

Objective:To explore the efficacy of using drug combination and sublingual immunotherapy（SLIT） for pediatric obstructive sleep apnea（OSA） and allergic rhinitis（AR） after adenotonsillectomy, in order to provide a more optimized treatment plan after the surgery. Methods:A total of 95 pediatric OSA combined with AR were selected. According to the treatment plan, they were divided into the SLIT group（postoperative medication combined with SLIT） and the control group（postoperative medication treatment only）. The comparisons were made between the two groups regarding the scores of the 18-item Quality of Life Questionnaire for Obstructive Sleep Apnea（OSA-18） and the Visual Analogue Scale（VAS） before and at 1 month, 3 months, 6 months, 1 year, and 2 years after treatment; the monthly total medication scores（TMS） from 1 month to 3 months, 4 months to 6 months, 7 months to 1 year, and 1 year to 2 years after treatment, as well as the number of acute attacks of AR in the 1st year and 2nd year after treatment; and the Lund-Kennedy scores and nasal resistance grading of nasal endoscopy before and at 1 month, 3 months, 6 months, 1 year, and 2 years after treatment. The effectiveness and safety were also analyzed. Results:After one year of treatment, the OSA-18 score, VAS score, TMS and Lund-Kennedy score in the SLIT group were significantly better than those in the control group. The nasal resistance was significantly reduced（P<0.05）, and the frequency of AR attacks was significantly lower than that in the control group（P<0.05）. After 2 years of treatment, the VAS score, Lund-Kennedy score and nasal resistance classification in the SLIT group tended to stabilize, while the OSA-18 score continued to decline. Conclusion:After surgery for pediatric OSA combined with AR, the use of drugs combined with SLIT can effectively alleviate AR symptoms, further improve OSA-related symptoms and quality of life, reduce drug dependence, decrease the frequency of AR attacks, and enhance the long-term efficacy of the surgery.
